Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the
configfs create dir() function that can lead to a memory leak. The issue arises from an incorrect reference count within the configfs make dirent() function, specifically when configfs create() fails. This failure path lacks a call to configfs d iput(), resulting in leaked memory associated with the subsystem and fragment. The memory leak was identified using kmemleak and observed during module loading (modprobe). The functions involved include kmem cache alloc, configfs new dirent, configfs make dirent, configfs create dir, configfs register subsystem, and configfs remove dirent.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
